SPECIFICATION forming part of Letters Patent No. 368,937, dated August so, 1887.

Application filed December 15, 1886. Serial No. 22l,614. (N0 model.)

To all whom it may concern.-

Be it known that I, CHESTER D. FLYNT, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of The essential'object of my invention is to obtain a lubricator of this character which shall possess superior durability and produce effective lubrication; to which end it consists in the novel features of construction hereinafter described, and illustrated in the accompanying drawings, in which- Figure l is a longitudinal section of a caraxle box, showing the lubricator in position therein, Fig. 2 is a cross-section of the lubricator detached. Fig. 3 represents a side view thereof. Fig. 4. represents a plan view thereof.

Similar letters of reference indicate corresponding parts.

The letter A designates the pad, and B the supporting-spring, of thelubricator. The body of the pad A is composedof sponge or other soft porous substance inclosed in a covering of fibrous or textile material, and it is of segmental shape in cross-section, thereby acconr modating itself to the journal of the axle. The spring B is attached to the bottom of the pad A by means of its top coil by stitching or other suitable means, and it is entirely surrounded by a wick, G, of fibrous or textile material, which is attached to the pad, together with the spring, the lower edge of said wick being secured to the bottom coil of the spring also by stitching or other suitable means.

When the lubricator is in position within To facilitate the introduction or removal of the lubricator it is provided with a handle, D, of flexible material, such as a piece of wicking, the ends of which are secured to the top and bottom coils of the spring, respectively.

By the construction of the pad A of sponge or other soft porous substance the serviceabilitylof the pad is not liable to be affected by the wear to which it is exposed in use due to the comparative indestruotibility and compact nature of the sponge, and hence the lubricator 6 possesses the greatest possible durability, while the material named is adapted to produce the required lubrication of the journal.

If desirable, the pad may be provided with additional pieces, E, of sponge orthe like on 6 within the spring may be wholly or partially filled with the same material, to act as a wick either in connection with or instead of the 7c body composed entirely of sponge or other soft 7 5 porous substance, and a suitable covering, in combination with a supporting-spring and wick, both secured to the bottom of the pad, substantially as and for the purpose described.

CHESTER D. FLYNT.
